Application filed July 19, 1917. Serial No. 181,545.

To all whom it may concern:

Be it known that I, LOUIS MIOKA, a citizen of the -United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Scrubbing-Brushes, of which the following is a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention has relation to improvements in scrubbing brushes; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

The present invention is particularly directed to brushes for scrubbing concrete floors, walls, and the like, though obviously not restricted in its application. The object of the improvement is to provide a brush (be the same made of bristles or other scrubbing material) to the rubbing face of which may be applied a stream of water with or without a complement of liquid soap or equivalent detergent in liquid or powdered form, suitable provision being made for cutting off the said soap and water supply when no longer needed. A further object is to provide the brush with a flushing attachment whereby the surface or floor when once scrubbed may be flushed with clean water from the same supply source which furnished the water to the brush. The advantages of the invention will be fully apparent from the following detailed description in connection with the accompanying drawings in which Figure 1 is a side elevation of my improved scrubbing brush; Fig. 2 is a top plan thereof; Fig. 3 is an enlarged vertical longitudinal section on the zigzag line 33 of Fig. 2; Fig. 4 is an enlarged vertical transverse section on the zigzag line 4-4; of Fig. 2; Fig. 5 is bottom plan of the brushsupporting easing detached; Fig. 6 is a vertical cross-sectional detail on the line 66 of Fig. 2, the valve bar and valves being in elevation; and Fig. 7 is a cross-sectional de tail of the two-way valve controlling the water supply.

Referring to the drawings, 1, represents a casing preferably (though not necessarily) rectangular in shape, the same being divided by a horizontal partiticm wall ordia-= 'phragm 2 into an upper shot compartment 3, and a bottom water compartment 4, a rubber band 5 encompassing the vertical walls of the casing and serving as a buffer to prevent the scratching of furniture and the wood work about the house. The shot compartment 3 is designed to be filled with cessity of bearing down on the same while scrubbing. The shot is introduced through a charging nipple or opening 0 in the roof of the compartment 3 normally closed by a screw-cap 6. Leading from the bottom of the water compartment 4 are outlet tubes 7 which are inserted through suitable openings designed to receive them in the back or brush mounting 8, the brush in the present embodiment of my invention being in the form of bristles 9 secured to the back 8 in any well approved manner known to the art. The casing 1 is provided with suitable tubular or hollow stays 10, 10 the former (10) spanning the space between the top and bottom walls of the casing and passing through the partition wall 2, the" latter 10) being similarly disposed but extending in addition a suitable distance above the top wall of the casing. The upper extension of the longer stay 10 is received by and forms a bushing for, the hollow stay or sleeve 11 connecting the top and bottom walls of a liquid or soft-soap holder or container 12, the soap or other form of detergent being poured into the holder through a filling nipple or opening 0 normally closed by a screw-cap 13. The stay 10 is traversed by the stem of a suitable bolt 14 the head h v of which is received in a socket or depression on in the bottom of the brush back or mounting 8, the stay 10 receiving the stem 7 of a corresponding but longer bolt 14. The upper threaded terminal of the bolt 14: is provided with a clamping nut n bearnrg against a washer w interposed between it and the top of the casing 1; and the upper end of the bolt 14: receives a nut n bearing against a washer w interposed between it and the top of the soap container 12.- The head 72/ of the bolt 14 is likewise received by a socket a in the brush-back 8 (Figs. 3,

4). The bolt 14, thus serves not only to secure and firmly clamp. the brush to the casing, but to clamp the soap holder to the casing, and hold the several parts firmly together.

Leading from the bottom of the soap holder are a pair of outlet nozzles 15 which are positioned to enter the upper terminals of the soap feed tubes 16 traversing the casing 1, said tubes passing through the partition wall 2 and discharging into the clearance or space 25 between the bottom wall of the casing (said wall being somewhat raised as clearly shown in Fig. 3) and the top wall of the brush-back 8. From the space 6 the soap flows through the passages 16 formed in the mounting 8 between the. bristles 9 (Fig. 3). The flow of the soap through the nozzles 15 is regulated by the reciprocating needle valves 17 depending from the opposite ends of a bar 18 mounted above the soap-holder, the valve stems playing freely through suitable openings provided therefor in the top wall of the soap holder. The bar 18 may be raised or lowered by means of a screw 19 the lower end whereof rests in a socket 20 formed on the top of the soap holder, the stem of the screw in the socket being provided with an annular groove 0? traversed by a set screw 6 passed through the socket wall whereby the screwis prevented from becoming loose. The threaded portion of the screw passes through a boss 2' on the bar 18 to afiord a larger purchase to the threads. By turning the screw 19 in proper direction the bar 18 and with it the valves 17 may be raised or lowered, and the flow of the soap through the nozzles 15 be accordingly regulated.

Disposed at the center of the casing 1 and spanning the shot compartment 3 thereof, and discharging directly into the water compartment 1, is a screw-threaded nipple 21 to which is secured an elbow 22. To the elbow 22 is coupled a water delivery pipe 23 serving as a handle for the brush, the upper end who 'eof terminates in a fitting 2 1 carrying a valve-casing 25 provided with a two-way valve .V manipulated by a handle L. The casing 25 is providedwith a branch tube 26 to which is coupled a flushing hose 27 terminating in a nozzle 28, the hose be ing supported by means of spring clips or clasps 29 carried by the pipe 23. The intake end of the casing :25 receives ashort length of pipe 30 to which the water supply hose H is directly coupled. The valve V is of ordinary construction and may be turned so as'toallow the water from the supplyhose H to flow either into the pipe 23 or into the 1 flush hose 27, or to cut ofithe water altogether, as clearly obvious from Fig. 7 of the drawings. No claim is made to the valve per 86.

The operation is clearly obviousfrom the lows: The valve V having been turned to the position shown in Fig. 7, water from the hose H flows under pressure through the pipe 23 into-the water compartment 41 of the casing 1, thence through the tubes 7 and into the spaces between the bristles 9. The operator at the same time turns the screw 19 sufhciently to raise the bar 18 and valves 17 to uncover the openings leading to the nozzles 15, the liquid soap in the holder 12 flowing through said nozzles 15, tubes 16, space if and out through the passages 16 bored in the mounting 8, the water and soap mingling between the bristles and supplying the necessary liquid for cleansing V purposes. When the surface has been thoroughly scrubbed, the valves 17 are seated, and the valve V turned ninety degrees to admit water into the hose 27, the latter being first detached from the supporting clips 29 (Fig. 2) the hose thus freed beingiused to flush the cleansed surface of all dirty water and soap. In using the device the compartment 3 is first filled with shot or lead balls 6 so as to weight the casing and brush and relieve the operator as much as possible.

I may of course depart in many respects from the details here shown without in anywise afiecting the nature or scope of my invention.

Having described my invention what I claim is:

1. In combination with a casing provided with a water compartment having an inlet and a discharge, a bristle brush secured to the casing and traversed by the water discharged therefrom means on the casing for feeding a suitable detergent to the brush, said detergent mingling with the water as it enters the bristles of the brush, means for cutting oil the water supply, and independent means for cutting ofl the supply of the detergent.
